Abstract

This research study proposes a combined filter-antenna design by employing stepped impedance resonator (SIR) techniques. The filtering antenna is designed around the unlicensed frequency band of 5.3 and 5.6 GHz. The filtenna realizes an insertion loss of −3.15 dB and return loss of −22 dB in the frequency band of 5.3 GHz and further −17.8 dB return loss in the 5.6-GHz band. The developed filtenna achieves omni-directional radiation pattern suitable for unlicensed applications with better selectivity and also results in low reflection loss. The observed voltage standing wave ratio is 1.6, and antenna gain is approximately 6.2 dBi in the 5.6-GHz band. The simulation results obtained align consistently with real-time measurements.

使用阶跃阻抗谐振器的紧凑型 6 千兆赫以下频带滤波贴片天线

这项研究通过采用阶梯阻抗谐振器（SIR）技术，提出了一种滤波器与天线相结合的设计方案。滤波器天线的设计围绕 5.3 和 5.6 千兆赫的非授权频段。滤波器天线在 5.3 GHz 频段的插入损耗为 -3.15 dB，回波损耗为 -22 dB，在 5.6 GHz 频段的回波损耗为 -17.8 dB。所开发的滤波器实现了适合非授权应用的全向辐射模式，具有更好的选择性，同时反射损耗也很低。观测到的电压驻波比为 1.6，天线在 5.6 GHz 频段的增益约为 6.2 dBi。模拟结果与实时测量结果一致。

期刊介绍： The International Journal of Communication Systems provides a forum for R&D, open to researchers from all types of institutions and organisations worldwide, aimed at the increasingly important area of communication technology. The Journal''s emphasis is particularly on the issues impacting behaviour at the system, service and management levels. Published twelve times a year, it provides coverage of advances that have a significant potential to impact the immense technical and commercial opportunities in the communications sector. The International Journal of Communication Systems strives to select a balance of contributions that promotes technical innovation allied to practical relevance across the range of system types and issues. The Journal addresses both public communication systems (Telecommunication, mobile, Internet, and Cable TV) and private systems (Intranets, enterprise networks, LANs, MANs, WANs). The following key areas and issues are regularly covered: -Transmission/Switching/Distribution technologies (ATM, SDH, TCP/IP, routers, DSL, cable modems, VoD, VoIP, WDM, etc.) -System control, network/service management -Network and Internet protocols and standards -Client-server, distributed and Web-based communication systems -Broadband and multimedia systems and applications, with a focus on increased service variety and interactivity -Trials of advanced systems and services; their implementation and evaluation -Novel concepts and improvements in technique; their theoretical basis and performance analysis using measurement/testing, modelling and simulation -Performance evaluation issues and methods.
